WQOD-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,421, dated November5, 1889.

Application filed December 22, 1888. Serial No. 294,372. (No model.)

To all whom it may concern.-

Be it known that I, MILON W. LIPE, of San Jos, Santa Clara county, Stateof California, have invented an Improvement in Wood-Sawing Machines; andI hereby declare the following to be a full, clear, and exactdescription of the same.

My invention relates to a machine for sawing wood in to short lengthsand carrying away the severed lengths as fast as they are out oif; andit consists of the construction and combination of devices which I shallhereinafter fully describe and claim.

Referring to the accompanying drawings for a more complete explanationof myinvention,Figure 1 is a top or plan View of the machine. Fig. 2 isa side elevation. Fig. 3 is an enlarged section showing more clearly thearran gement of the rack upon the carriage and the pinion by which it isdriven, also the fric- IlOIL-WhGGlS.

A is the frame, having a boiler B and suitable engine from which poweris derived, and through the belt 0 is transferred to the pulleyD uponthe saw-arbor E, which is journaled upon the frame.

F is the movable table or carriage, mounted upon the frame A in suitablerelation to the saw G. Beneath this carriage F is fixed a rack H. Ashaft I is journaled across the frame A at a suitable point,'so that itliesbeneath the table F, and this shaft has fixed upon it a pinion J insuch a position that the teeth of this pinion will engage with the teethof the rack H, and when the shaft I is caused to revolve it will,through its pinion J and the rack H, act to move the carriage F forward,so that the wood which is laid upon this carriage will be fed to the sawG, so as to be out without the operator exercising any pressure to forcethe stick against the saw, which labor becomes very irksome whencontinued for a long time.

In order to move the table F, or to stop it at will, a friction-wheel Kis mounted upon a shaft I, and the second wheel L is fixed upon theshaft M, so. that it may be brought into contact with the wheel K, orthrown out of contact at the pleasure of the operator. The shaft M isdriven by a belt N from the engine, passing around a pulley 0 upon thisshaft, so that the shaft is kept in continuous motion.

In order to move the frictional wheel K into contact with thefriction-wheel L, it is necessary to make one end of the shaft Imovable, the other end being loose enough in its journal-box' to allowof the slight movement necessary for this purpose. The end of the shaftI which is nearest to the frictionwheel K turns in a journal-box P,which is fitted upon the main frame A with slotted extensions, and pinspass through the slots in these extensions, as shown at Q, so that thebox P may have a limited movement horizontally. When moved in onedirection, it will bring the wheel K in contact with the moving pulleyL,and thus rotate the shaft I and the pinion by which the carriage F ismoved. In order to move this journal-box, the extension at the right ofthe box, as shown in Fig. 1, is connected by a pin with a slotted arm R,which projects upwardly from the shaft S, j ournaled upon the frame. Thecrank-arm T upon this shaft is connected by a rod or cord U with thetreadle V.

The operation of this device will then be as follows: The end of thestick to be sawed is laid upon the table F, and the operator placing hisfoot upon the treadle V depresses it, thus pulling upon the crank-arm Tand turning the shaft S. By turning this shaft the slotted arm R willact to draw the journal-box P, and with it the end of the shaft I andthe wheel K, until the Whole comes in contact with the rotatingfriction-wheel L, and thus turning the wheel K and the pinion J, whichwill actupon the rack H, and thus draw the table F along and advance thestick against the saw as fast as it is out until it is severed. Theoperator then releases the treadle V, and by means of the weight 'W,connected with the carriage F in any suitable manner, and with directionpulleys, this weight Will act to return the carriage to its originalposition. along for a new cut, and the billet which has been cut off ismoved by this action so as to fall upon the endless inclinedcarrier-belt X, the frame of which is journaled at the side of the frameA and close to the table F. A shaft Y, journaled upon the main frame A,

The stick is then pushed extends outward from this frame and hassprocket-wheels Z fixed upon it, so as to drive the chainsof the endlessbelt X. The beveled pinions a-one upon the shaft Y and the other uponthe shaft M-serve to give motion to this mechanism.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a sawing-machine, a saw-arbor journaled upon the main frame, carryingthe saw, a movable feed-table with a rack and a pinion mounted upon ashaft carrying a friction- Wheel and movable so as to be engaged with ordisengaged from a corresponding rotating friction-wheel, as described,in combination with the crank-shaft, one end of which is connected withthe movable box of the pinion-- shaft and the other with a treadle,whereby contact between the two friction-wheels is made or broken, and aweight connected by a cord with the table so as to return it to itsnormal position after the friction-Wheels have been disengaged,substantially as described.

In witness whereof I have hereunto set my hand.
